How to Determine if an Egg is Fresh?

Fill a container up with warm water. I use warm water. The reason
for this is that eggs are porous. If you put an egg in cold water, it will
contract and draw any bacteria that is on the outside of the shell in
through the pores. This is not good. So, if you use warm water, the
egg will expand, and you will notice that little air bubbles form on
the shell.

Put your eggs into the warm water, and look at them. A very fresh
egg will sink to the bottom and lay on is side. Week old eggs will
rest on the bottom but the fat end of the egg will rise up slightly.
Three week old eggs will be balanced on pointy end with the fat
end sticking up. Old eggs will be floating, bobbing along the surface
of the water. These floaters should be tossed as they aren't any good
to eat.
